Effect of side‐chain length on the electrospinning of perfluorosulfonic acid ionomers
Journal of Polymer Science Part A: Polymer Chemistry, 2012AbstractThe effect of the side‐chain length (short side chain and long side chain, SSC and LSC, respectively) of perfluorosulfonic acid (PFSA) ionomers on the properties of nanofibers obtained by electrospinning ionomer dispersions in high dielectric constant liquids has been investigated with a view to obtaining electrospun webs as components of fuel ...

Inclusion Abilities of Bile Acids with Different Side Chain Length
Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2001Abstract It was found that steroidal bile acids have greatly different inclusion abilities with decreasing or increasing their side chain length. Namely, the acids with intermediate side chains formed inclusion compounds with various organic compounds, while those with shorter or longer chains did not include so many.

Side-chain liquid-crystalline copolymers containing spacers of differing lengths
Macromolecules, 1992Copolymers [CH 2 CHPh(R 1 )] 0.5 [CH 2 CHPh(R 2 )] 0.5 (R 1 = O(CH 2 ) 8 OPhN=NPhOMe; R 2 = O(Ch 2 ) n OPhN=NPhOMe n = 3-12) are prepared and compared with the homopolymers [CH 2 CHPh(R 2 )] m . All the polymers exhibit smectic behaviour with the exception of the homopolymer with n = 3for which no mesophase was observed.

Die Makromolekulare Chemie, 1985
AbstractA series of soluble polymers was prepared by copolymerization of the 4‐nitrophenol ester of N‐methacryloylated ω‐amino acids (1a – i), of N‐methacryloyldiglycine (2b), of 6‐(N‐methacryloylglycylamino)‐ and of 6‐(N‐methacryloylglycylglycylamino)hexanoic acid (3a and 3b) with N‐(2‐hydroxypropyl)methacrylamide (HPMA).

The effect of isoprenoid side chain length of ubiquinone on life span
Medical Hypotheses, 2003The isoprenoid side chain length of ubiquinone (Q) can have an effect on the life span of mammals. The short living mouse and rat have Q(9), while primates have Q(10) as the major form. Ubiquinones (Qs) having longer hydrophobic tail are likely more imbedded in the mitochondrial inner membrane than the ones having shorter tails.

Microphase separation of comb copolymers with two different lengths of side chains
Physical Review E, 2009The phase behavior of the monodisperse AB comb copolymer melt contained the macromolecules of special architecture is discussed. Each macromolecule is assumed to be composed of two comb blocks which differ in numbers of side chains and numbers of monomer units in these chains.

Controlling the mechanical properties of hydrogels via modulating the side-chain length
Soft Matter, 2023Even though the toughness of hydrogels is usually adjusted by changing the cross-linking density and structure, or the polymer concentration, we have discovered a new strategy to control the toughness via modulating the side-chain length.

On the relation between side chain length and RM value
Journal of Chromatography A, 1959Abstract A study was made of the R M values, given in the literature, of a wide variety of organic compounds forming homologous series. An equation is proposed in which the R M value is related to the number of carbon atoms in the members of the homologous series.

Polymerized ionic liquid diblock copolymers with long alkyl side-chain length
Polymer, 2014Abstract A polymerized ionic liquid (PIL) diblock copolymer with a long alkyl side-chain, poly(MMA- b -MUBIm-Br), was synthesized at various compositions from an ionic liquid monomer, (1-[(2-methacryloyloxy)undecyl]-3-butylimidazolium bromide) (MUBIm-Br), and a non-ionic monomer, methyl methacrylate (MMA).

Side Chain Length-Dependent Dynamics and Conductivity in Self-Assembled Ion Channels
The Journal of Physical Chemistry C, 2022We study the molecular mobility and electrical conductivity of a homologous series of linear shaped columnar ionic liquid crystals ILCn, (n = 8, 10, 12, 14, 16) using broadband dielectric spectroscopy (BDS), specific heat spectroscopy (SHS), and X-ray scattering.
